The snow removal machine shall be designed to clear sno
33、w off traffic areas and deposit it targeted aside or load it on a vehicle platform. The mounting shall be possible on vehicles with standards according to EN 15431 and EN 15432-1. 5.2 Quality of clearing The snow removal machine shall attain an even clearing pattern. The following characteristics ar
34、e essential here: smooth running characteristics; adjustment according to profile and angle of the clearing area; adjustment of clearing speed (see 5.5); equipment for targeted snow throw-out; use of suitable scraper blades, sliding equipment or castor wheels; maximum utilization of drive power for
35、clearing performance; BS EN 15906:2011EN 15906:2011 (E) 12 clearly organized and logical control elements. 5.3 Snow removal performance 5.3.1 General The measuring of the snow clearing capacity is based on the amount of snow removed over time. For a precise gauging the following parameters shall be
36、taken into account: measurement period; clearing width; clearing height; removal speed; average snow density; consistency of the snow; throw-out distance; throw-out direction. 5.3.2 Requirements for testing snow removal performance Snow density : average from 3 vertical measuring points from every 1
37、0 m horizontal intervals (see Figure 4) left and right along the removal measuring path. Every volume specimen should be at least min. 0,001 m (specimen diameter = 0,1 m). Throw-out distance: throw-out direction should be 90 to the removal direction and horizontal to the deposited snow. Measuring di
38、stance is between the main focus point of the deposited snow and the middle of the snow removal machine (see Figure 5). Snow pick-up and snow deposition should be on the same height level. Measurement period: at least 1 minute or one measuring path of minimum 30 m. The clearing height shall remain c
39、onstant during the measuring procedure. The measurement shall be performed over a continuous application. The phase of starting the snow removal before the measuring distance shall not be taken into the calculation. The throw-out distance to determine the maximum clearing capacity shall be between 5
40、 m and 10 m.

45、be caused by foreign objects in the snow (e.g. stones). The safety mechanisms can be a mechanical, hydraulic or other system. Parts that wear, such as shear-bolts, shall be easy to replace. 5.5 Removal speed A minimum removal speed of 0,1 m/s shall be possible at full power. 5.6 Throw-out control Ta
46、rgeted snow-throw shall be possible. The control for this should be actuated remotely. 5.7 Raising and lowering of snow removal machines The snow removal machine shall allow, independent of the vehicle, a raising height of 200 mm. In addition, the snow removal machine shall allow a lowering of 100 m
47、m under the traffic area. 5.8 Support while working The snow removal machine shall be able to adapt to the unevenness of the sub-grade or to smoothen to a targeted level. Suitable supports (sliding shoes, castor wheels, etc.) or respective control is to be used. Parts that wear should be simply chan

In transport position, a lock shall prevent the machine against unintentional lowering. The necessary view of the driver to the traffic area shall be guaranteed also in transport position. 5.10 Operation with the communal hydraulics of the carrier vehicle When operating with the commun
